9.8CVSS
En pocas palabras
Esta vulnerabilidad se puede explotar a distancia, a través de la red, sin credenciales, sin que la víctima haga nada. Un ataque exitoso compromete gravemente la confidencialidad, la integridad y la disponibilidad del sistema.
Descripción texto oficial en inglés
WWBN AVideo 6.5 through 29.7.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user via Hybridauth social login display names. Attackers can set their X, Facebook, Yahoo or LinkedIn display name to a victim's username and withhold email, causing login.json.php or oauth2.php to log them in as that account, including administrators, without a password.
